Web alarm clock for 4:16 a.m.
You wake at 4:16 am with the night ferry still ahead and the pier not yet reached. Set this alarm so you have enough time to get dressed, check your bag, and arrange the trip to the waterfront before the vessel arrives. With 5:00 am approaching, those quiet minutes can keep the start of your journey calm rather than rushed.
Your ferry pickup depends on hearing the alarm after you have set it, so keep this browser running on a device that will remain awake until 4:16 am. If the screen locks deeply, the computer sleeps, or the browser closes, the ferry reminder may make no sound. Leave the volume at a level you can hear, and test the sound before lying down again.
After meeting the ferry at the pier, protect the sleep that remains by preparing a direct return to bed. Keep the room dim, place fresh water and your keys where you can find them, and avoid starting chores when you come home. A short, planned night interruption is easier to contain when everything needed for the waterfront trip is ready before you rest.
